SINOTOP STDC programmable BLDC motor controller provides efficient, smooth and quite controls for golf cart, go-cart, electric motorcycle, forklift, hybrid vehicle, electrical vehicle, electric boat, as well as industry motor speed or torque control. Motor speed controller uses high power MOSFET, PWM to achieve efficiency 99% in most cases. Powerful microprocessor brings in comprehensive and precise control to BLDC motor controllers. This programmable brushless motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.

Features:
• Intelligence with powerful microprocessor.
• Synchronous rectification, ultra low drop and fast PWM to achieve very high efficiency.
• Current limit and torque control.
• Battery current limiting available, doesn’t affect taking off performance.
• Low EMC.
• LED fault code helps user deb ing.
• Battery protection: current cutback, shutdown and warning at high or low battery.
• R ed aluminum housing for maximum heat dissipation.
• Thermal protection: current cuts back on low temperature and high temperature to protect battery and controller.
• Configurable 60-degree or 120-degree hall position sensor.
• Any number of poles supported.
• Up to 60000 electric RPM. (Electric RPM = mechanical RPM * motor poles)
• Three modes of regen: brake switch regen, release throttle regen, 0-5V signal regen.
• High pedal protection: Disable operation if power up with non-zero throttle.
• Current multiplication: Take less current from battery, output more current to motor.
• Easy installation: 3-wire potentiometer will work.

Optional Features:
• PWMable Reverse Alarm.
• Brake Switch for regeneration.
